A length (L 1 ) of the overall sealing liner including the radially smaller portion and the radially enlarged portion is defined as a first length. A length (L 2 ) of said radially enlarged portion is defined as a second length. A ratio of the first length to the second length is between about 6.5 and about 8.5.
